Case Study Remote Control of Longwall Mining

2010-1-11 · "Longwall" mining differs from "Room & Pillar" mining in that the mine roof is expected to fall when operations are concluded in a particular area of the mine. For this reason, roof supports are not as extensive at the working mine face. This holds obvious danger to the miners operating at the fine face using the mining machines called "shearers".

Cutting Machines Shearers Introduction

Once fully into the web, the shearer can advance the full length of the face cutting out the web. The snake can also be reversed to cut the wedge shaped portion of coal left while sumping in. The first shearers had a single drum rigidly attached to the body of the machine and so had a fixed cutting height and had to be able to get the body of the machine past the edge of the
